Senior Electrical Design Engineer

What You Will Do

Senior Electrical Engineer responsible for electrical analysis, detailed design, controls integration, and overall electrical performance of HVAC equipment, including air handlers, fan coils, and blower coils.

This role supports new product development, sustaining engineering, prototyping, laboratory validation, and manufacturing execution across air handling, fan coil, and VAV platforms.

Responsibilities include:

• Defining system‑level electrical architectures, performing load analyses, and coordinating protective devices for HVAC equipment platforms.
• Designing and reviewing electrical schematics, wiring diagrams, harnesses, and developing panel, enclosure, and junction layouts that support manufacturability, serviceability, and thermal performance.
• Integrating motors, VFDs, EC motors, controllers, sensors, actuators, and control interfaces across line‑ and low‑voltage systems.
• Developing and maintaining electrical engineering standards, parts libraries, specifications, and design rules for configurable products and dynamic BOM generation.
• Interpreting and applying electrical safety and compliance requirements (NEC, UL1995, UL60335‑2‑40) to ensure designs meet agency requirements for wiring methods, protection, accessibility, and markings.
• Creating and maintaining agency listing documentation, supporting certification testing, and working with internal compliance teams and third‑party agencies to resolve non‑conformances.
• Supporting A2L refrigerant programs, including refrigerant detection system integration, alarm and control responses, and sensor location coordination.
• Partnering with the test laboratory to define and execute electrical test plans validating motors, drives, heaters, controllers, and safety devices.
• Analyzing test results, identifying root causes, and driving corrective actions.
• Collaborating with sourcing to deliver production‑ready electrical BOMs, qualify new suppliers and components, and support cost and obsolescence mitigation.
• Supporting manufacturing engineering with DFMA improvements to ensure successful transition from design to production.
• Providing electrical guidance to applications engineering, sales, service, and field teams regarding product capabilities, installation constraints, and troubleshooting.
• Leading and participating in continuous improvement initiatives to reduce design cycle time and increase engineering throughput.
• Mentoring junior engineers and designers to ensure consistent application of engineering standards and best practices.

• Bachelor’s Degree or equivalent in Electrical or Controls Engineering.
• 5+ years of electrical engineering experience in HVAC or a closely related product‑based manufacturing environment.
• Proficiency creating 2‑D electrical schematics using AutoCAD or similar tools, with the ability to interpret drawings, diagrams, and wiring requirements.
• Experience working with electrical bills of material, component databases, and engineering documentation systems.

• Hands‑on experience supporting prototype builds and laboratory testing of motors, drives, heaters, controllers, and safety devices.
• Familiarity with A2L refrigerant detection systems, wiring practices, and control responses.
• Experience supporting configurable product platforms and dynamic BOM logic.
• 3D CAD experience with Solid Works.
• Working knowledge of NEC, UL1995, and UL60335‑2‑40 as applied to equipment wiring, protection devices, and accessibility.
• Prior experience mentoring engineers or designers.
